The third coronavirus outbreak in the last two decades has caused significant damage to the world’s economy and community health. The highly contagious COVID-19 infection has affected millions of people to date and has led to hundreds of thousands of deaths worldwide. Aside from the highly infectious nature of SARS-CoV-2, the lack of a treatment or vaccine has been the main reason for its spread. Thus, it has become necessary to find alternative methods for controlling SARS-CoV-2. For the present review, we conducted an online search for different available nutrition-based therapies for previously known coronavirus infections and RNA-based virus infections as well as general antiviral therapies. These treatments have promise for combating COVID-19, as various nutrients and minerals play direct and indirect roles in the control and prevention of this newly emerged viral infection. The patients’ nutritional status with COVID-19 must be analyzed before administering any treatment, and nutritional supplements should be given to the affected individuals along with routine treatment. We suggest a potential interventional role of nutrients to strengthen the immune system against the emerging infection caused by COVID-19.

Foodborne pathogens have acquired the ability to produce biofilms to survive in hostile environments. This study evaluated biofilm formation, antimicrobial resistance (AMR), and heavy metal tolerance of bacteria isolated from dairy and non-dairy food products. We aseptically collected and processed 200 dairy and non-dairy food specimens in peptone broth, incubated them overnight at 37 °C, and sub-cultured them on various culture media. Bacterial growth was identified with biochemical tests and API 20E and 20NE strips. The AMR of the isolates was observed against different antibacterial drug classes. Biofilm formation was detected with the crystal violet tube method. Heavy metal salts were used at concentrations of 250–1500 µg/100 mL to observe heavy metal tolerance. We isolated 180 (50.4%) bacteria from dairy and 177 (49.6%) from non-dairy food samples. The average colony-forming unit (CFU) count for dairy and non-dairy samples was 2.9 ± 0.9 log CFU/mL and 5.1 ± 0.3 log CFU/mL, respectively. Corynebacterium kutscheri (n = 74), lactobacilli (n = 73), and Staphylococcus aureus (n = 56) were the predominant Gram-positive and Shigella (n = 10) the predominant Gram-negative bacteria isolated. The correlation between biofilm formation and AMR was significant (p < 0.05) for most cephalosporins, aminoglycosides, and fluoroquinolones. Heavy metal tolerance tended to be higher in biofilm producers at different metal concentrations. The pathogens isolated from dairy and non-dairy food showed a high burden of AMR, high propensity for biofilm formation, and heavy metal tolerance, and pose an imminent threat to public health.

Blood transfusion-transmitted infections in individuals suffering from beta-thalassemia have been reported in Pakistan, but the information on their sociodemographic and clinical determinants is lacking. This study aims to describe the prevalence, as well as the factors, contributing in blood transfusion-transmitted infections. Between December 2011 and December 2013, in a non-probable sampling, 350 thalassemia patients were recruited in Lahore, Multan, Karachi and Peshawar, Pakistan. Subjects were screened for transfusion-transmitted infections. A seropositive rate of 36.5% was observed; males (94, 73.4%) and females (34, 26.6%). Among several risk factors associated with transfusion-transmitted infections, province (p=0.001), gender (p=0.003), age (p10 years were significantly more prone to seropositivity than those aged ≤10 years. Moreover, the ferritin level was also significantly higher in those aged >10 years than in those ≤10 years. It was observed that males had a higher seroprevalence rate (94, 73.4%) than females (34, 26.6%). The most prevalent transfusion-transmitted infections was the hepatitis C virus, with 115 cases (89.8%). A high prevalence rate of HCV in subjects with transfusion-dependent thalassemia is linked with insufficient facilities, poor management and compromised socioeconomic status. Therefore, more multicenter studies covering cities from different regions of the country are needed in order to develop preventive measurements at the regional and national level.
Compromised quality of life (QoL) has been reported in individuals suffering from beta-thalassemia major (beta-TM) in Pakistan. However, insufficient data of its associated psychosocial, physical and other disease-related determinants is available. In an observational analytical study, 200 subjects aged between 5-25 years, were examined using a transfusion-dependent QoL (TranQoL) questionnaire. Clinical records and other related data were also gathered from transfusion center databases. The TranQoL mean score was 48.33 +/- 5.6, ranging from 53.86 +/- 13.6 for family functioning and support domain to 39.70 +/- 18.4 for school and career functioning domain. Age, income, education, pre transfusion hemoglobin (Hb), serum ferritin level, pain, death due to beta-thal, monetary issues and pain were significantly associated with TranQoL scores. It was not only the clinical conditions but life alterations, social relationship and psychological events also loomed in improvement of treatment outcomes. Therefore, a tetra-cone of patient, school representatives, family and physicians are needed for better patient prospective.
